sMRM Pro Builder template tutorial

The sMRM Pro Builder template is an Excel-based tool that can help you implement large panels of analytes in your lab. The Excel sheet will take your preliminary experimental results and compute retention times, retention time window widths and dwell time weighting to optimize your targeted assay.

What is the difference between MRM3 vs MS/MS/MS (MS3)?

The MRM3 workflow and the MS3 scan are functionally the same QTRAP system scan, but used with different goals in mind.  The main difference is how these scans are used in the whole MS workflow. With MS3 scans, you can use these in a data dependent mode for discovery...

How do I define the experimental design (the metadata) for my SWATH acquisition study within the OneOmics suite? What are the requirement for replicates?

How do I define the experimental design (the metadata) for my SWATH acquisition study within the OneOmics suite? What are the requirement for replicates?

In quantitative Omics research, the goal is to understand which analytes (protein or metabolite) are perturbed between experimental conditions; therefore we carefully design our studies to explore these questions. The algorithms used within the Assembler application...

A rising star in food allergen research: proteomics of shellfish allergen

A rising star in food allergen research: proteomics of shellfish allergen

It’s important to know what you’re eating, especially if you suffer from a food allergy.

About 220 million people worldwide live with a food allergy.1 These numbers, along with the complexity and severity of conditions, continue to rise. In America, there are about 32 million food allergy sufferers—5.6 million of those are children under the age of 18.2.2 That’s 1 out of every 13 children, or about 2 in every classroom. From a financial perspective, the cost of food allergy childcare for US families is up to $25 billion

Detect the Signal, Not the Noise

  Improving the specificity and selectivity of your assay Your LC-MS assay is only as good as its power to discern your target compound from everything else. Standards dissolved in clean solvents can make beautiful assays, but analytes in real-world samples can behave...

Make the Leap from GC to LC-MS/MS

  Choosing the best technique for your analysis can be tough. Should you go with gas chromatography/mass spectrometry (GC-MS) or liquid chromatography/tandem mass spectrometry (LC-MS/MS)? That’s the key question. That’s why we’re here to help. The Limitations of...

Uncovering the Links Between Childhood Growth, Body Size, and a Woman’s Risk of Breast Cancer

Uncovering the Links Between Childhood Growth, Body Size, and a Woman’s Risk of Breast Cancer

Welcome to the second in a series of posts marking International Women’s Day, and our ongoing support of World Cancer Research Fund. This installment is a review by Dr. Jennifer Baker, of her work, that, with the help of a WCRF grant, is studying body size and its links to breast cancer. Dr. Baker, Lead Investigator at Denmark’s Frederiksberg Hospital, has a Ph.D. in Human Nutrition from Cornell University. Her research focuses on clinical epidemiology.

Data Independent Acquisition Mass Spectrometry with the Power of SWATH

Data Independent Acquisition Mass Spectrometry with the Power of SWATH

There are many different methods in use today to acquire data on a mass spectrometer, but few have generated as much buzz in recent years as SWATH technology. First reported 5 years ago by Ruedi Aebersold and his group1, SWATH® Acquisition on a TripleTOF® instrument has rapidly become one of the premier acquisition strategies for identification and quantitation of complex samples. But what exactly is SWATH and why is it so powerful? In order to answer these questions, let’s first take a step back and look at the larger picture.

Vice President Biden Announces Agreement Naming Children’s Medical Research Institute’s ProCan Lab to the ‘Cancer Moonshot’ Initiative

Vice President Biden Announces Agreement Naming Children’s Medical Research Institute’s ProCan Lab to the ‘Cancer Moonshot’ Initiative

A key goal of the ‘Cancer Moonshot’ initiative is the advancement of precision medicine, with the goal of making more targeted therapies available to more cancer patients. And researchers believe that the time is right, with the new technological innovations, the new insight into the biology of cancer and big improvements in the handling of ‘big data.’

Stoller Biomarker Discovery Centre, Addressing Some of the Biggest Issues in Medicine

The Stoller Biomarker Discovery Center, developed in partnership with SCIEX, was created to develop new omics technologies for biomarker research to understand the root cause of diseases such as cancer, cardiovascular disease, and autoimmune diseases. We initially announced our collaboration with the University of Manchester back in October 2015. 

The History of Isotopic Labels for Quantitative Proteomics

The History of Isotopic Labels for Quantitative Proteomics

Proteomics has become a vital tool for biological scientists performing research on the healthy and diseased states of living things. It involves the large scale and systematic analysis of all proteins within a given cell, tissue, or organism. Because proteins are regulated by many different internal and external stimuli, the proteome is dynamic and quantities of proteins can change from one state to the next. Therefore, in order to be of the highest utility, proteomics experiments need to both identify and quantify proteins so that comparative studies can be done, such as between healthy cells and tumor cells, or the comparison of different treatment regimens.
